Closed Cell spray foam, often referred to as 2 pound foam, has unique qualities that make it a perfect insulator for almost any area in the home. Closed Cell is made of millions of closed cells that trap a gas that is lighter than air giving it a much higher R-value per inch than other insulations with R-values ranging from 6.5-7.5/inch. Closed Cell is great at mitigating moisture which makes it a great insulation for below-grade walls, wine rooms, saunas, indoor pools, corrugated steel decks, and other areas where moisture control is important. Closed Cell also is much stronger than open cell and can add structural integrity to a house with older framing and can be used as under slab insulation prior to pouring concrete. In addition, closed cell foam is FEMA Class 5, the highest rating for flood resistant materials.
Our Closed Cell foams pass Appendix X 377 to be left exposed without an ignition barrier in attics and crawlspaces without storage. Like most Closed Cell foams, you still need a 15-minute thermal barrier if foam is left exposed and the area will be used for storage. Check with your local building inspector.
